My thoughts, as someone who has read 6 of the books, are as follows:

AAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH YEEEEEEESSSSSSSSSSSSSSS OH FUCK OH FUCK HOW DID I MISS THIS!!!!!!! SANCTUARY MOON!!!! MENSAH!!!! AAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

I would have picked someone a little bit more non descript or androgynous, but you know what, I'll TAKE IT. Skarsgard is not a mega hunk and he's a good actor.

Oh my God I'm so excited.
